  1. run nix build --impure "nixpkgs#bash"

nix (Nix) 2.9.0pre20220411_f7276bc

instantiated 'bash-5.1-p16' -> '/nix/store/zmlniq7rkz4mq0bb07wyzpj4k65nm6hf-bash-5.1-p16.drv'
evaluating uncached attribute 'legacyPackages.x86_64-linux.bash'
evaluating uncached attribute 'legacyPackages.x86_64-linux.bash.meta'
evaluating uncached attribute 'legacyPackages.x86_64-linux.bash.meta.outputsToInstall'
